Participants

Reaction Steps

The title compound was prepared analogously to step 5 of example B(29)where 4-(4-ethoxycarbonyl-butyl)-piperidine-1-carboxylic acid tert-butyl ester from step 3 above, was substituted in place of 3-[5-chloro-6-(cyano-dimethyl-methyl)-pyridin-3-yl]-propionic acid ethyl ester in that example. 1H NMR (400 MHz, CDCl3): δ 1.07-1.39 (m, 7H), 1.45 (s, 9H), 1.59-1.70 (m, 4H), 2.33-2.38 (m, 2H), 2.64-2.68 (m, 2H), 4.09-4.12 (m, 2H). ESIMS (MH−): 284.
